tmr2 interrupt problem

[ADCON]

hi, the counter3 has not to be the problem. It is incremended everytime it go's to the ISR. If you look at the top of the ISR you see:

if counter3=>200 then 'number of shiftouts
counter3=0
else 
counter3=counter3+1
endif

So it stays in stat loop until the ISR is called for 'counter3' time's.
So it's a kind of delayloop.

Is there an other wat to go to the ISR at the timerinterrupt then ON INTERRUPT?

I go to try comment the code to a minimize is left and use 'return' at th end of the ISR.

To make clear that there are no mistakes: I tried to make the program work in loops and every time the timerinterrupt sets it's flag jumps it to the ISR to shiftout the displayvalues, afther that it go's back to twere it was en finish the loop so it can start again waiting for a buttonpress.

I'm sorry, I thing it will be tomorrow that this is finished. It's buzy over here...

i changed my code now.
the var counter works fine.

LOOP:


Sec=12
Mins=34
hr=56

if counter3=>100 then
blink=1
else 
blink=0
endif
goto loop
end

This is with only the return-command.

I'm going to change the loop now. I try to set more gosubs in it, maby it works..

[s]It looks like there is a problem between the I2C and interrupt. Do's I2C also use timer2 for it's clocksignal or something?[/s]
edit:
I found a mistake:
@ loop:
goto coldstart

@ coldstart
return



not all the problems are solved now, but at least return at the end of the ISR dos have any effect!

edit2:
after changing the tris settings to
TRISA=%11111111
TRISB=%11111111
I can make some input with the buttons. The problem now is that it's menu is not working right.
It looks like it just runs the routine for once and not wait for any other input.(possible a mistake when I did change it from only loops to interrrupt I might have did something wrong..). I have to look at that for now..

None of I2C function use the internal timer, but they need time to execute. I should be able to build the board today.

Out of curiosity... did you also tried to test it with ISIS?

[ADCON]

I have no licence of ISIS. If I had I would be happy
Well, I have now the clock working(it means running the way it has to do) and it looks like the settings of the menu is now a software-thing what I have to debug and modificate. My old version did work but to make it timerinterrupt I had to change the code. So, I think I have make some mistakes at that part of the job. It looks like it runs the menu for one time and don't wait for inputs.
For this part thanks for all your help!

It is a option to use also a interrupt for the inputbuttons...

[ADCON]

Well, its working finally!

The only thing is that the display dos not change when a button is pushed-in. so, when you hold your hand on a button so it will count crom 1,2,3,4 and release it by five, you see the 1 untill you release the button.
I have to finish that part..
